Security Assertion Markup Language (SAML) authentication workflows not present for some customers

Summary: Security Assertion Markup Language (SAML) authentication workflows not present for some customers Description: Mitigation work is currently underway by our engineering team. Steps have been taken to reduce the impact of the issue in us-east1 and eu-west1 by our engineering team. We do not have an ETA for full mitigation at this point. We will provide more information by Wednesday, 2023-02-08 09:30 US/Pacific. Diagnosis: Some users are unable to login with SAML on Edge and Apigee Portals and SAML login button does not appear on the login page for some users. Users may also see the error message "Metadata issuer for https://sts.windows.net/xxx/ wasn't found" or "Validation of protocol message signature failed" when attempting an SAML login. Workaround: None at this time.
